STRAINER FOR WELLS.

To all whom it may concern:

Be it known that we, JOSEPH I]. BOONE and EMANUEL BOONE, J12, citizens of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Strainer for \Vells, of which the following is a specification.

This invention relates to strainers for wells;

and it has for its object to provide a strainer for Artesian and other tubular wells which shall be simplein construction, and which may be readily placed in position aft-er the well has been drilled and lined.

. The invention consists in the improved construction of the said straining device, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a vertical sectional view of our improved straining device, showing the same in position for operation at the bottom of a well. Fig. 2 is a horizontal sectional view taken on Fig. 3 is a perspective detail view showing the upper portion of our improved strainer and adjacent parts, portions of the same having been removed for the purpose of better showing the construction. Fig. 4 is a similar view showing the lower end of the strainer. Fig. 5 is a horizontal sectional view showing a modification.

The same letters refer to the same partsin all the figures of the drawings.

Our improved strainer is composed of a series of vertical longitudinal metallic rods or bars, which may be triangular or trapezoidal in cross-section, and which are connected together by securing them to the outer edges or peripheries of a series of metallicrings B B, which are provided with notches or recesses O, forming seats for the said bars, which are to be firmly secured by means of soldering or in any other suitable manner in the said seats in such a manner that their outer edges shall be very close to the other, and yet the rings B, which separate the notches C in said rings, may be provided with outwardlyextending nibs or projections E, adapted to SPECIFICATION forming part of Letters Patent No. 415,607, dated November 19, 1889. Application filed May 29, 1889. Serial No. 312,626. (No model.)

extend through notches F, formed in the rods or bars A, which latter may then be secured to the rings B by riveting or clinching the projecting ends of the nibs E, as will be seen in Fig. 5 of the drawings. In this manner the rods or bars A may be secured to the connecting-rings B in an exceedingly rigid and substantial manner and without the use of brazing or soldering. the supporting-rings B I), are preferably to be made of brass, although other suitable'noncorrosive metal may be substituted.

vIt will be seen that by connecting the bars The bars A, as well as A A together in the manner described they will form a complete cylindrical strainer. The lower end of this is exteriorly screwthreaded and provided with a solid cap G, the lower end of which may be made tapering, as shown in Fig. 1 of the drawings, so

that the device may be readily placed in position, as will be presently more fullydescribed. The upper end of the cylindrical strainer is likewise screw-threaded and provided with a collar II, the outer side of which is made tapering, as will be clearly seen by reference to Fig.1 of the drawings. Thecollar II is provided with an interior annular flange I, adapted to bear against the upper edge of the cylindrical strainer, as shown in Fig. 1.

J designates the well-casing, the lowerend of which is provided with an annular shoe or collar K, constructed of steel and having a tapering inner side adapted to form a seat for the collar II at the upper end of the strainer, the outer side of which is to be ground so as tofit tightly in the said seat.

In operation, after drilling and lining the well our improved strainer may be brought into the lining. The lining 0r casing is then lifted or partially withdrawn until the shoe K at its lower end reaches the annular collar H, which automatically drops into its seat in the said shoe. tion for operation.

It is sometimes necessary to take water from all of theveins through which the well may pass, and in such cases it will be found nec- The device is then in posiessary to use a strainer of considerable I00 length. In such cases the cap Gat the lower end of the strainer may be removed and any such a manner as to enable them to resist any pressure which may be brought to bear upon them, either by caving of the well or from other causes. It will also be seen that our improved strainer may be readily placed in position for operation, and that when once in position it is not liable to become accidentally displaced.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. A strainer for Artesian or tubular wells, comprising a series of vertical longitudinal triangular or trapezoidal bars mounted in notches or recesses in the outer edges of a series of connecting and bracing rings, substantially as and for the purpose set forth.

2. The combination, with a strainer composed of a series of longitudinal vertical bars mounted in recesses in the outer edges of a series of connecting-rin gs, of a solid exteriorly-beveled cap mounted upon the lower end of said strainer, substantially as set forth.

The combination, with a cylindrical strainer comprising a series of vertical longitudinal bars mounted in recesses in the outer edges of a series of connecting-rings and having an exteriorly-screw-threaded lower end, of an interiorly-threaded cap mounted detachably 011 the lower end of said strainer, substantially as herein set forth.

4. A tubular strainer comprising a series of vertical longitudinal bars mounted in recesses in the outer edges of a series of connecting-rings and having screw-threaded upper end, in combination with a sleeve or col lar mounted upon the upper end of said strainer and havingan interior annular flange bearing against thesame, substantially as herein set forth.

5, A tubular strainer comprising a series of longitudinal bars mounted in recesses in the outer edges of a series of connecting-rings and having screw-threaded upper end, in combination with a sleeve or collar mounted upon the upper end of said strainer and having a beveled or tapering outer side, and an interiorly-tapering shoe or collar secured at the lower end of the Well casing or lining and forming a seat for the collar at the upper end of the strainer, substantially as herein set forth.

6. A cylindrical tubularwell strainer comprising a series of vertical longitudinal bars mounted in recesses or notches in the outer edges of a series of connecting-rings and provided at its lower end with a solid cap and at its upper end with an exteriorly beveled or tapering collar having an interior annular flange bearing against the upper edge of said strainer, in combination with an interiorly beveled or tapering shoe attached to the lower end of the Well casing or lining and forming a seat for the tapering collar at the upper end of said strainer, substantially as herein set forth.

7. In a cylindrical tubular-well strainer, the combination of a series of connectingrings having notched or toothed outer edges, with the longitudinal vertical straining-bars mounted in said notches or recesses and retained therein by the clinched or riveted outer ends of the teeth separating said notches, substantially as set forth.

8. The combination, With the connectingrings having notched or toothed outer edges, the teeth of which are provided with outwardly-extending nibs or projections, of the longitudinal vertical straining-bars adapted to be seated in the notches of the said connecting-rings and provided with notches for the passage of the nibs or projections of the teeth of the latter, substantially as and for the purpose herein shown and specified.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in presence of two Witnesses.
